#cqww Experimental realtime propagation PE4BAS

Just as experiment I want to make a chart and display the number of WSPR spots for some continents. Just to see what propagation is like on 20m just before the CQWW SSB contest. I tried to make a prediction for our contestlocation but it seems to be difficult if you don't know exactly how propagation will behave next days. This night there was a huge radio black out on the HF bands and so far my 1W signal on 20m has not been spotted anywere at nighttime! Surprisingly I spotted a station from Chile south america this night. Below a chart I will try to update through the day with new info. In 24 hours there will be a complete graph over de day on 20m. Spots are combined spots received and transmitted (1W).

Above the propagation at Thursday 27-October-2016. Well the chart is complete now and I want to continue tommorow with a new one. I think it gives usefull info about when a certain part of the world can be heard and worked. Nothing seen from Asia, Japan or Australasia today. Hopefully propagation is rising a bit we'll have a look at it tomorrow.

Above the chart at 28-October-2016

Although it seems propagation is rising a bit (1 spot from Japan seen, yesterday nothing) it is still very low.

Looking at the sunspot numbers today is only 12 with high A and K values. The red line above is the estimated (forecast) sunspot number. It should be rising! The green dots representing real values measured.
